can ~; it’s okay if ~ (compromise)
Expresses that it is permissible or acceptable if a certain condition occurs, often implying a compromise or concession.
This pattern is used to say that even if something happens, it won't cause a problem. It's a formal way to say 'it's okay if...' or 'you can...' and often appears in official notices, polite suggestions, or when granting permission with a nuance of compromise. For example, if you say '遅れても差し支えない', you mean that being late won't be an issue; it's acceptable. The pattern is quite stiff and literary, so in everyday conversation you'd usually use 'てもいい' instead. It can also be phrased as 'ても差し支えありません' for extra politeness.
